tkcon license

[Wart]

The license for tkcon is very similar to the TCL license, except that
the sentence about relicensing with modifications is missing:

"Modifications to this software may be copyrighted by their authors
and need not follow the licensing terms described here, provided that
the new terms are clearly indicated on the first page of each file where
they apply."

This doesn't seem to me to be objectionable (the bourbonware clause is cute, 
though).  I'm just not sure if I should still call this the 'TCL' license, if 
it should be added as a variant of the TCL license, or call it something else.
